The world’s first AR fully shielded by WMD’s proprietary NiB-X® nickel boron extreme coating process providing unmatched reliability and increased functionality—inside and out! NiB-X® is not a paint, it is a performance coating harder than hard chrome with coefficient of friction near Teflon.

Lesser ARs are much more vulnerable to moisture, corrosion, lubricant buildup, and powder fouling. But the 5.56 Beast from WMD is practically unstoppable, thanks to our NiB-X® coating technology. NiB-X® not only guards against friction and wear, it virtually eliminates feeding problems associated with buildup of lubricant and residue.

The rifle comes with two magazines, one NiB-X® 30 round magazine and a polymer magazine. and is packed in a ballistic fabric tactical bag, the Beast is ready for extreme performance in any environment, with MOA potential right out of the box.

In accuracy testing this rifle liked: Federal 69gr Match Kings = .75 moa at 200 yards Hornady 55gr FMJBT = 1.25 moa at 100 yards Federal American Eagle 55 gr FMJBT = .50 at 100 yards
